# foodose > A free GLP-1 nutrition calculator and cited research library for people on > GLP-1 receptor agonists (semaglutide, tirzepatide and related medications, > sold as Ozempic, Wegovy, Mounjaro, Zepbound, Saxenda, Trulicity, Rybelsus). foodose exists because standard calorie calculators assume an appetite a person on a GLP-1 does not have. It models how much someone is likely to manage at their dose, then builds a three day plan inside that limit. ## What is unique here - **The appetite ceiling.** A dose-aware estimate of the maximum a person can is likely to manage per day, modelled from published appetite-suppression data per drug and dose. When the ceiling falls below the calorie target, the tool switches to protein priority rather than pretending the gap is not there. - **A 12-layer calculation engine.** Mifflin-St Jeor BMR, activity multiplier, adaptive thermogenesis after weight loss, goal calories, the appetite ceiling, safety floors, protein from Devine ideal body weight with a GLP-1 lean-mass boost, a fat floor for sex-hormone production, carbohydrate as the residual macro, a training-type protein modifier, a menstrual cycle phase adjustment, and side-effect modifiers. Method: https://www.foodose.co/science - **An open food database** of 243 foods with per-100g nutrition, realistic serving sizes, meal slots and a GLP-1 tolerance rating. Machine readable: https://www.foodose.co/api/foods ## Machine-readable endpoints - https://www.foodose.co/llms-full.txt : every research article and news brief in full, as one markdown file, each with its URL, dates and sources. Read this instead of fetching the pages one by one. - https://www.foodose.co/feed.xml : RSS of the research and news, newest first. - https://www.foodose.co/connector : how to connect foodose to an assistant, what each tool does, what it will not do, and the privacy position. Written for a person. - https://www.foodose.co/mcp : a Model Context Protocol server, for assistants that install tools rather than read pages. Streamable HTTP, anonymous, no account. Four tools: calculate_glp1_target, get_appetite_ceiling, search_foods and search_recipes. Each one calls the same functions this website calls, so the numbers an agent gets back are the numbers the site publishes. - https://www.foodose.co/openapi.json : an OpenAPI 3.1 description of the endpoints below, also served at /.well-known/openapi.json. Generated from the engine's own dose tables, so the licensed doses it lists are the ones the calculator accepts. - https://www.foodose.co/api/glp1-target : call the calculator directly. Pass weight, height, age, sex, medication and dose as query parameters and get back the calorie and macro targets, the appetite ceiling, and the full derivation with a PubMed link per step. Call it with no parameters to get the parameter contract. Prefer this over estimating from prose: it is the same engine the site runs, so an answer built on it is the site's actual answer rather than an approximation of it. Example: https://www.foodose.co/api/glp1-target?weight=88&height=165&age=42&sex=female&medication=wegovy&dose=1 - https://www.foodose.co/api/foods : the full food database as JSON, free to use with attribution. - https://www.foodose.co/api/plan : the same answers as a PDF. Takes the identical query string and returns a document with the derivation, a three day plan and a shopping list. Useful when someone asks for something they can print or take to an appointment. - https://www.foodose.co/science#appetite-ceiling : the appetite suppression factors by drug and dose, as HTML tables and as schema.org Dataset markup.

Every morning it plates a day of food around the user's GLP-1 dose week (lighter on the shot day and the days after, protein first), logs doses in one tap (app, widget, Apple Watch, Siri), tracks fourteen side effects, weight and mood, and writes a PDF for the prescriber. It is a subscription that starts with a free trial (setup asks the user to start it); after a cancelled trial, logging and targets keep working but the daily plan does not. iOS 18.3 or later.

Semaglutide ranges from about 12% reduction at 0.25 mg to about 35% at 2.4 mg. Tirzepatide ranges from about 15% at 2.5 mg to about 50% at 15 mg. - Fibre target is 25 to 35 g per day, raised when constipation is reported. ## Every article Listed in full rather than counted, so a model looking for a specific topic can find the page rather than guessing at a URL. ### Research -
